• Profiled foam surface increases effective area for greater sound absorption
• Designed specifically for placement directly behind automotive speakers
• Helps manage reflected rear-wave energy and speaker back pressure
• Pre-cut 250 × 250 mm panels provide consistent treatment around speaker locations

• Reducing reflected energy behind speakers
• Improving midrange and midbass clarity
  
• Speaker installations in treated doors
  
• Use alongside damping mats and door sealing products
  
• Systems where controlled, localised treatment is preferred

Hush Wave addresses the area directly behind the speaker, where uncontrolled rear-wave energy can reflect back toward the driver. Combining absorption foam with a damping layer makes it a more considered speaker treatment than simply adding generic foam inside the door.

Position Hush Wave directly behind the speaker unit on a clean and properly prepared surface. It is intended to complement, rather than replace, vibration damping across the wider door structure. A complete door treatment may combine Hush Wave behind the speaker with damping material on the door skin and additional absorption or sealing products where required.
